An object is to obtain an aqueous primer that offers excellent preservation stability and, when printing images, text, etc., to form a printing layer on a plastic film or other nonabsorbent medium using inkjet recording ink compositions, allows for formation of a printing layer having high adhesion, capable of forming high-quality images with little bleeding/mottled appearance, and offering excellent water resistance and lamination suitability. The solution is to provide: an aqueous primer composition containing a water-soluble multivalent metal salt, a polyester-based polyurethane emulsion, and water; a set including the aqueous primer composition and an inkjet recording ink composition; and a printed matter comprising a base material layer, a primer layer containing a water-soluble multivalent metal salt and a polyester-based polyurethane, and a printing layer.
